CAUSES OF KICKBACK

Kickback can occur when the blade stalls or binds, kicking the workpiece back toward you with great force and speed. If your hands are near the blade, they may be jerked loose and contact the blade.

Obviously, kickback can cause serious injuryand it is well worth using precautions to avoid the dsks.

Kickback can be caused by any action that pinches the blade in the wood, such as the following:

Making a cut with incorrectblade depth

Sawing into knots or nails in the workpiece

Twistingthe wood while making a cut

Failing to supportwork

Forcing a cut

Cuttingwarped or wet lumber

Misusingthe saw

Not followingcorrectoperating procedures

Using the wrong blade for the type of cut

Cuttingwith a dull, gummed-up, or impropedyset blade.

AVOIDING KICKBACK

Always use the correct blade depth setting. The outer point of the blade teeth shouldclear the lower surface of the workpiece by 1/8 in. to 1/4 in. when makingthese cuts.

Inspectthe work for knots or nails before beginning a cut. Knockout any loose knots with a hammer.

Never saw into a loose knot or nail

Always use the fence when dp cutting.This helps prevent twistingthe wood in the cut.

Always use clean, sharp, and properly-setblades. Never make cuts with dull blades.

To avoid pinchingthe blade, supportthe work propedy before beginning a cut.

When making a cut, use steady, even pressure, Never force cuts.

Do not cut wet or warped lumber.

Always hold your workpiece firmlywith beth hands or with pushsticks.Keep your body in a balanced position to be ready to resist kickback shouldit occur. Never stand directly in line with the blade.

Use the righttype of blade for the cut being made.

Use the rivingknife and anti-kickback pawls when performing ripcuts.
